Title: Servo circuit
Inventor: SHINOHARA TORU
IPC: H02P25/06
Filed: 1989-01-10
Abstract: PURPOSE:To reduce the rounding of an accelerated current at the time of small difference and to shorten a velocity control time by changing the cut-off frequency of a velocity error generation circuit respectively during acceleration and deceleration. CONSTITUTION:An acceleration detection circuit 9 is provided to detect the execution of the acceleration from the output of a velocity error generation circuit 5 and according to the under-acceleration detecting signal of this acceleration detection circuit 9, the cut-off frequency of the velocity error generation circuit 5 is changed respectively during the acceleration and deceleration. During the acceleration, the cut-off frequency is made infinitely large or large, and during the deceleration, the cut-off frequency is made small. During the acceleration, even when the cut-off frequency is infinitely large or large, the oscillation of a mechanism (servo object) is hardly generated. Then, the cut-off frequency is made large the rounding of the accelerated current is reduced and an acceleration period is shortened. During the deceleration, since the cut-off frequency is returned to be small, the oscillation of the mechanism is not generated. Thus, the rounding of the accelerated current is reduced at the time of the small difference and the velocity control time can be shortened.

Title: Frp structural body
Inventor: KAWAMURA KUNIHISA
IPC: B29L31/00
Filed: 1990-01-11
Abstract: PURPOSE:To obtain an FRP structural body having the sufficient rate of absorption for impact energy by forming a plurality of opening parts on a metallic sheet along the lengthwise direction and burying this metallic sheet into the wall part of a cylindrical body made of FRP in the length wise direction thereof. CONSTITUTION:A foam 4 becoming a urethane core is formed and glass fiber (continuous fiber) is wound thereon. Metallic sheets 3 having the circular opening parts 5 are inserted into the respective faces of this foam 4. Thereafter the foam 4 is arranged into a forming mold. The molding composition made of both unsaturated polyester resin for base material resin and glass fiber for reinforce fiber is introduced and an FRP structural body 1 is obtained which has the outer shell of FRP 2. At this time, a metallic sheet 7 having the rectanglar opening parts 6 whose end parts are formed into a semicircular shape may be utilized. Further the metallic sheet 8 having the opening parts 5 and 6 may be utilized. When this FRP structural body receives impact along the lengthwise direction, the cylindrical body made of FRP is not ruptured but continuously destroyed because the metallic sheet with the opening parts formed thereon is buried into the wall part of the cylindrical body made of FRP. Therefore impact energy is successively absorbed.

Title: Phase shifter
Inventor: MIYASHITA KAZUHITO
IPC: H01P1/18
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To linearly change the inserting amount and phase change amount of a dielectric by setting the square roots of specified effective dielectric constants of a line which is not inserted with the dielectric, first dielectric and line to insert a second dielectric in specified relation concerning the line composed of two conductors for inserting the movable dielectrics in lengthwise direction and setting the length of the first dielectric to a specified value. SOLUTION: When the square root of the specified valid dielectric constant of the line which is not inserted with the dielectric is defined as n0 and the square roots of the specified effective dielectric constants of the lines to insert the first and second dielectrics are respectively defined as n1 and n2, the sclation n1=(n0.n2)<1/2> is established, and when the wavelength in vacuum is defined as λ0, a length L1 of the first dielectric is set so as to establish the rclation L1=λ0/4/n1. Since the reflected waves at both the terminals of the first dielectric are canceled at all times and waves are reflected only from the terminal of the line, the phase change amount can be expressed by a linear expression to the inserting amount of the dielectric, and when controlling the phase change amount through an external circuit, circuit configuration can be simplified.
